The Bellamy salute is the salute described by Francis Bellamy, Christian socialist minister and author, to accompany the American Pledge of Allegiance, which he had authored. During the period when it was used with the Pledge of Allegiance, it was sometimes known as the “flag salute”. Later, during the 1920s and 1930s, Italian fascists and Nazis adopted a salute which had the same form, and which was derived from the Roman salute. This resulted in controversy over the use of the Bellamy salute in the United States. It was officially replaced by the hand-over-heart salute when Congress amended the Flag Code on December 22, 1942.

Just plain wow.
